“…They are widely used in Italy (Sesia, 2000) but they are neverthless toxic and able to form metabolites retaining significant toxicological properties (Nelson et al, 1981;Foran et al, 1985;Baron and Merriam, 1988;Moye and Miles, 1988;Gupta, 1994;Canna-Michaelidou and Nicolau, 1996;Alvarez-Rodriguez et al, 1997). Moreover, carbamates show a high mobility in soil Fava et al, 2001) and have been detected in significant concentrations in groundwater (Williams et al, 1988;USEPA 1984;IHP, 1998;Walker and Porter, 1990;Jones and Estes, 1995;Funari et al, 1995). Since they have significant biological properties (Gupta, 1994), they can represent a human health hazard, especially if the water is used for drinking.…”

Degradation studies in soil of the insecticides aldicarb and carbofuran and their metabolites (aldicarb sulfoxide, aldicarb sulfone; 3-ketocarbofuran and 3-hydroxycarbofuran) were carried out using laboratory systems under controlled conditions (temperature, water content, light). The insecticides were added to soil samples and subsamples of the soil were analyzed at different times to assess both the bacterial abundance and the concentration of the different chemicals. The epifluorescence direct count method was applied to the subsamples to estimate microorganism numbers (N=g soil). Untreated samples of soil were used as controls for evaluating the effects of the application of the insecticides on microbial abundance. Subsamples treated with the pesticides were analyzed using HPLC and the DT 50 s of the different compounds studied were calculated.The DT 50 values show that neither the parent compounds nor the transformation products have a high persistence in soil and there is a general increase in the concentration of microorganisms as the pesticides diminish.

“…These include numerous state monitoring programs, national monitoring programs conducted by the EPA as well as the NAWQA program conducted by the USGS, and a variety of registrant monitoring and research studies. The work from 1979 through the mid-1980s shows that aldicarb residues have the potential to move into groundwater under certain conditions, but that residues in drinking water can be prevented by a number of best management practices including use restrictions in highly vulnerable areas, optimization of timing and rates of application, and well setbacks (Jones and Estes, 1995).…”

“…The rate of transformation of aldicarb sulfoxide and aldicarb sulfone strongly depends on the conditions in the aquifer material. Residues of these compounds have been found in the groundwater of some areas, but not in that of others 26. Unfortunately, the geochemical conditions in the different sampled aquifers were poorly characterized.…”

Laboratory and field studies show that pesticides may be transformed in the groundwater zone. Possible reaction mechanisms are chemical hydrolysis, catalytic reduction and aerobic or anaerobic microbial transformation. Transformation in the groundwater zone can be an important element in the advanced evaluation of the potential risk arising from a pesticide in the public drinking water supply. However, rate and pathway of transformation can show large differences, depending on the bio-geochemical conditions in the groundwater zone. Knowledge of the reaction mechanisms and the effect of aquifer conditions would allow vulnerable and low-vulnerable application areas for a pesticide to be delimited. An outline is given of possible approaches to quantifying these transformation processes and using the results in registration procedures, especially in the EU and its member states. Furthermore, areas where there is need for continued research and better understanding are highlighted.
